Gentlemen,
some time ago I had the possibility to buy a surplus HP5359 Time
Synthesizer. As far as I can judge from my measurements with a HP5370
and a SR620 the two delays that are generated inside the box with high
precision are ok and completely within the specs, which is the most

Does anybody have their Thunderbolt working directly with ntpd?
The documentation for ntpd says the Palisade driver has been updated to work
with the Thunderbolt. It has a config option (mode 2) to use 8N1 and a few
other changes. I haven't looked carefully at the code.
I'm pretty sure my

Your HP 5359A observations are normal, and many other HP 5359A users have
asked exactly the same question, down through all these years since the box

*only* to generate precise timing. The box wasn't intended to

Does anyone know the current status of NTPD with NMEA PPS drivers on

will be running this OS. Now I need to work out whether it will be my
time server or whether an additional lightweight BSD

Hi,
Has anyone determined how an interface could be incorporated into the
Thunderbolt so as to show if it was locked. Some status led's would be nice
such as can be fount on the Z3801's front panel.

I have written a little (2500 line) C program that parses all the Thunderbolt

Larry,
Et al,
So long as the unit is a VP, the firmare date should not matter. The last
firmware for the VP was v10.0 and was released in 1997, but all VP firmware
will work with the HP's. As you can see from the TAC32 screenshot on Ebay
the receiver being used was a 6 channel VP with v8.4
Are you sure it's a 1530a? I used to work for Austron, but don't recognise
that model number.

Thanks, Randy, for the history lesson on the VPs and their firmware.
My previous firmware comment, however, was directed at the Z3801A's
motherboard firmware, not the VP's firmware. This is because my Z3801A won't
take a manually entered date after Dec 31st, 2007. With a 2008

Not a problem. The VP works fine with current dates. The ones you have to
look out for are back in the original v6.x firmware days. Because of their
programming the were not capable of handling the 1024 week rollover.

Interesting. Thanks.
What is a pendulum oscillator, and what changes while one is sitting idle?
Why does it change more than a normal quartz oscillator?

Hal,
A pendulum oscillator is not that different. Basically it is a quartz
oscillator that is pulled by an electronic circuit, not unlike a VXVCO. As
any crystal does, it ages as it sits around, and depending on how well it

The Thunderbolt does not produce NMEA messages, so you would need to parse the
